and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a plan view of our invention. Fig. 2 is a vertical longitudinal section, and Fig. 3 is a vertical transverse section, of the same.

This invention relates to machines for cleaning cotton in the boll-that is, separating the trash, dust, and dirt from it preparatory to ginning. It consists, essentially, in the combination, with a horizontal chamber, having the interior configuration of the fiustum of a cone, and the lower half of its wall composed of separated longitudinal rods or grating, of a heater, consisting of a helical row of arms radiating from a central shaft, and increasing in length toward the larger end of said.

chamber, for the purpose of insuring the steady discharge from the chamber of the cotton after it has been sufficiently operated upon. I

Within a suitable oblong case, A, is arranged horizontally a concave, B, consisting of longitudinal rods 0, having spaces D be tween them, thus forming a grating. Said concave forms the lower half of the chamber heretofore referred to. It is closed at its narrow end I) and open at its wide end b, and, in form, flares gradually toward said wide end, which terminates on a lower level than the said narrow end, over which is arranged the inlet or receiving opening 6 in the top of the upper half. E of the cleaning-chamber. This upper half E has a continuous inner wall,

a, but is flat on top, and is hinged longipulley, f.

Surrounding the shaft F is a helical row of arms, G, which increase in length toward the wide end of the chamber.

When the machine is in operation this helical row of arms beats and cleans the cotton, and, also, acting as a propeller-screw, gradually forces the mass toward the wide open end of the concave, where the cleaned bolls are discharged.

It will be seen that clogging of the cleaning-chamber, while the machine is in operation, cannot occur when the beating-arms are arranged as just described.

The outer wall of the upper hinged halfchamber is a wooden casing, the top H of which inclines downward toward the narrow end of the chamber, and is entirely surrounded by a rim, h, thus forming a hopper, from which the receiving opening or inlet 6 leads into the cleaning-chamber. A large quantity of cotton may be piled upon the top of the machine, and, owing to the inclined position of said top, may be fed into the cleaningchamber with great facility.

As the cotton is beaten and cleaned, the trash and dirt, which are removed therefrom by theaction of arms G, fall through the spaces D between rods 0 into the lower part of case A, and may be raked out through the fall-doors I, hinged so as to open from a level with the bottom of case A.

Having thus fully described the construction and operation of our invention, we claim 1. The combination of the closed half-chamber E, grated flaring concave B, having its wide end open, and shaft F, provided with a helical row of arms, .G, and increasing in have hereunto subscribed our names in the length toward the discharging end, substanpresence of two Witnesses.
